Deleting old logon accounts

I am cleaning up the logon accounts on a backup server.

When I try to delete account X, i am prompted to replace the account becuase it is being used by current jobs\selection lists.

The two jobs it is refering to are restore jobs (2 of them).

I tried looking these in the current jobs and selections lists, but didnt find these two jobs anywhere.

Is this normal behavior?  Can i just replace the creds and delete that account?
